[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, an ejection assembly for an automobile body mold includes a stamping table 1, the back of the stamping table 1 is fixedly connected to a fixed plate 2, the top of the front of the fixed plate 2 is fixedly connected to a top plate 3, the bottom of the top plate 3 is fixedly connected to a hydraulic rod 4, the bottom of the hydraulic rod 4 is fixedly connected to a stamping plate 5, and the rear side of the surface of the stamping plate 5 is fixedly connected to a lifting frame 6. A through slot 22 is opened on the front of the fixed plate 2, and the lifting frame 6 extends to the rear side of the fixed plate 2 through the through slot 22. The bottom end of the lifting frame 6 is located at the bottom of the stamping table 1, and a bottom plate 7 is provided at the bottom of the stamping table 1. , both sides of the top of the bottom plate 7 are fixedly connected with top columns 8, a stamping groove 9 is opened in the middle of the surface of the stamping table 1, and top holes 10 are passed through on both sides of the bottom wall of the stamping groove 9. The top columns 8 are located inside the top holes 10 and are slidably connected thereto, and both ends of the surface of the stamping table 1 are fixedly connected with mounting plates 11, and the inner side of the mounting plates 11 is fixedly connected with an electric telescopic rod 12, and the output ends of the electric telescopic rod 12 are fixedly connected with a splint 13. A start button 14 is provided on the front side of the surface of the stamping table 1, and the start button 14 is connected to the electric telescopic rod 12 signal.

[0021] refer to Figure 3 , springs 15 are fixedly connected to both ends of the top of the base plate 7, the tops of the springs 15 are fixedly connected to the bottom surface of the stamping table 1, and damping rods 16 are provided inside the springs 15. The bottom surfaces of the damping rods 16 are fixedly connected to the surface of the base plate 7, and the tops of the damping rods 16 are fixedly connected to the bottom surface of the stamping table 1.

[0022] As a technical optimization solution of the present invention, the spring 15 and the damping rod 16 are provided to provide limiting support for the bottom plate 7 and the top column 8. At the same time, after the hydraulic rod 4 drives the stamping plate 5 and the lifting frame 6 to press down, the spring 15 and the damping rod 16 can drive the surface of the top column 8 and the bottom wall of the stamping groove 9 to remain at the same horizontal plane, so that the bottom plate 7 and the top column 8 complete automatic reset, avoiding affecting the stamping of the workpiece. At the same time, the damping rod 16 makes the spring 15 drive the bottom plate 7 to reset and rebound more stably, and will not rock back and forth, so that it will not affect the stamping of the workpiece, making the ejection assembly run more stably.

[0023] refer to Figure 2 The inner side of the splint 13 is fixedly connected with an anti-skid pad 17, and the surface of the anti-skid pad 17 is fixedly connected with a plurality of anti-skid convex strips, which are distributed in a linear array. The anti-skid pad 17 and the anti-skid convex strips are both made of rubber.

[0024] As a technical optimization solution of the present invention, the provision of the anti-slip clamping pad 17 greatly increases the friction between the clamping plate 13 and the workpiece, thereby avoiding the situation where the workpiece shifts when the punching plate 5 descends to punch the workpiece, resulting in stamping failure and waste of the workpiece.

[0025] refer to Figure 2 , both sides of the inner wall of the through slot 22 are provided with limiting slots 18, and the left and right sides of the lifting frame 6 are fixedly connected to the limiting blocks 19, and the limiting slots 18 are located inside the limiting blocks 19 and are slidably connected thereto.

[0026] As a technical optimization solution of the present invention, the moving path of the lifting frame 6 is limited by the setting of the limit groove 18, making its up and down movement more stable, so that when the lifting frame 6 moves up to push out the workpiece, the force it applies is more uniform, thereby avoiding the uneven stress at the connection between the stamping plate 5 and the lifting frame 6, which leads to the problem of reduced service life and easy detachment.

[0027] refer to Figure 4 A circular groove 20 is provided on the rear side of the surface of the stamping table 1 , and a reset button 21 is provided inside the circular groove 20 . The reset button 21 is connected to the electric telescopic rod 12 by signal.

[0028] As a technical optimization solution of the present invention, through the setting of the reset button 21, the stamping plate 5 can drive the lifting frame 6 to descend when stamping the workpiece, and the top wall of the lifting frame 6 will fit into the reset button 21 and gradually press it completely. After the reset button 21 is fully pressed, the electric telescopic rod 12 will contract to release the workpiece, thereby facilitating the lifting frame 6 to drive the bottom plate 7 and the ejector column 8 to automatically eject the workpiece when retracting, thereby eliminating the step of manually operating the electric telescopic rod 12 and further improving the ejection speed and efficiency.

[0029] refer to Figure 2 and Figure 4 The cross-sectional area of the stamping plate 5 is the same as that of the stamping groove 9 , the stamping plate 5 is slidingly connected to the stamping groove 9 , the thickness of the stamping plate 5 is the same as that of the stamping groove 9 , and the reset button 21 is located on the rear side of the stamping groove 9 .

[0030] As a technical optimization solution of the present invention, the reset button 21 is located on the rear side of the stamping groove 9, which avoids contact between the stamping plate 5 and the reset button 21. At the same time, the lifting frame 6 can fit the surface of the stamping table 1 to fully press the reset button 21 downward, thereby ensuring that the electric telescopic rod 12 can be stably retracted, further improving the stability of the ejection assembly.

[0031] The working principle and usage process of the present invention are as follows: when in use, the user first places the workpiece on the inner side of the two clamping plates 13, and presses the start button 14 to extend the electric telescopic rod 12 to drive the clamping plate 13 to move and thereby clamp the workpiece tightly, and then control the hydraulic rod 4 to drive the stamping plate 5 to stamp the workpiece. At the same time, the stamping plate 5 will drive the lifting frame 6 to descend, so that the bottom wall of the lifting frame 6 is separated from the bottom plate 7, and the top wall of the lifting frame 6 will fit with the reset button 21 and gradually press it completely. After the reset button 21 is fully pressed, the electric telescopic rod 12 will drive the clamping plate 13 to contract and release the workpiece. After the stamping is completed, the hydraulic rod 4 drives the stamping plate 5 to reset. At this time, the stamping plate 5 will drive the lifting frame 6 to rise, and the lifting frame 6 will fit with the bottom plate 7 and push it upward. The bottom plate 7 then drives the top column 8 to move upward, and the workpiece that has completed partial stamping inside the stamping groove 9 is lifted upward, so that the workpiece can be easily taken out.
